      Comparison of reflectance confocal microscopy and line-field optical coherence tomography for the identification of keratinocyte skin tumours

      Background: Reflectance confocal microscopy (RCM) and line-field confocal optical coherence tomography (LC-OCT) are non-invasive imaging devices that can help in the clinical diagnosis of actinic keratosis (AK) and cutaneous squamous cell carcinoma (SCC). No studies are available on the comparison between these two technologies for the identification of the different features of keratinocyte skin tumours. Objectives: To compare RCM and LC-OCT findings in AK and SCC. Methods: A retrospective multicenter study was conducted. Tumours were imaged with RCM and LC-OCT devices before surgery, and the diagnosis was confirmed by histological examinations. LC-OCT and RCM criteria for AK/SCC were identified ...

    2. Delayed Tattoo Reaction From Red Dye With Overlapping Clinicopathological Features: Examination With High-Frequency Ultrasound and Line-Field Optical Coherence Tomography

      Delayed Tattoo Reaction From Red Dye With Overlapping Clinicopathological Features: Examination With High-Frequency Ultrasound and Line-Field Optical Coherence Tomography

      Introduction Delayed tattoo reactions include a wide range of clinical presentations and overlapping forms; thus diagnosis can be challenging. We present a case of a delayed tattoo reaction from red dye. Case Presentation An otherwise healthy 40-year-old man presented with firm elevated plaques that arose 4 months previously, within a multicolored tattoo on the right forearm, 8 months after the execution of the tattoo ( Figure 1A ). The patient claimed minimal and only occasional itching. Polarized dermoscopy (Luminis Visiomed, Caliber) highlighted multiple keratotic plugs within the lesion, limited to the red-dyed areas ( Figure 1 ). Examination with line-field confocal optical coherence tomography ...
